Adds a Makefile to fill dependencies for testing.

Depends upon pip being installed, but pip is pretty much
the standard nowadays and is just an easy_install away if
it isn't there.

The only dependency installed on to the system is
virtualenv which is used to make the other dependencies
local to the current environment.

Does not remove the need to install redis by hand, though
I am in favor of making that possible (using aptitude on
linux and brew on os x)

I look forward to cutting away at some of these
dependencies in further commits.
Move virtualenv installation out of the makefile.

Also adds some tools for dealing with virtualenvs to the tools
directory.
Fixes to the virtualenv installer
resolving conflict w/ merge, cleaning up virtenv setups
Added exit code checking to process.py (twisted process utils).  A bit of class refactoring to make it work & cleaner.
Also added some more instructive messages to install_venv.py, because otherwise people that don't know what they're doing will install the wrong pip... i.e. I did :-)
Added Cheetah to pip-requires
adding pep8 and pylint for regular cleanup tasks
Greater compliance with pep8/pylint style checks
Run correctly even if called while in tools/ directory, as 'python install_venv.py'
2 changes in doing PEP8 & Pylint cleaning:
 * adding pep8 and pylint to the PIP requirements files for Tools
 * light cleaning work (mostly formatting) on nova/endpoints/cloud.py

Note: On my laptop, I had two tests failing just with a basic setup. I checked against all the tests again after cleanup, and had no additional or different failures.
Changes the run_tests.sh and /tools/install_venv.py scripts to be more user-friendly and not depend on PIP while not in the virtual environment.  Running run_tests.sh should not just work out of the box on all systems supporting easy_install...
Quick fix on location of printouts when trying to install virtualenv.
Oops, we need eventlet as well.
